Answer:
The correct answer is: <em>B. blood cells would be in a hypotonic solution, so water would rush into the cell causing it to expand and eventually burst</em>.
Explanation:
Cells have a certain solute concentration that produces an osmotic pressure of aproximately 300 mOsm. For that reason, IVs solutions must have a solute concentration which equals the cell osmotic pressure. That is usually acomplished by using an aqueous solution of NaCl 0.9% w/v or 5% w/v Glucose.
If an IV of pure water is administrated to a person, the blood cells will be in a hypotonic solution. That is, with a concentration lesser than the concentration inside the cells. Due to the difference in concentration, a net flow of water will be produced from the exterior to the cell interior. As the volume of the cell is increased, the cell membrane is damaged and eventually the cell will collapse.

Answer:
The independent variable is "controlled" or held constant in the control group. A single experiment may include multiple experimental groups, which may all be compared against the control group. The purpose of having a control is to rule out other factors which may influence the results of an experiment.
Explanation:
<span>Solar and wind is the list that contains the only examples of renewable sources of energy. Solar energy is generated by using sunlight while wind energy is generated by using wind turbines. Hence both of these energies does not require any form of burning of fuels and hence are renewable sources of energy.</span>
